I shall take a datalog tomorrow and post it here.


Thanks.

Hurray!
I finally have AFR in my datalogs. Managed to smooth the cruising AFRs but its pretty erratic on otherwise.

Hi,
I have also the AEM 30-0300 wideband on the Kpro v4.
But I see on the lambda overly the voltage in the KManager 4.4.3.... Did I have something configured wrong? It will not converted into the AF or lambda readings... :-(

Kpro <> Analog_Gauge wiring KManager configuration:
Can someone tell me whats wrong? I think I did not have correctly configured the KManager to display the valid data. But I could not find the issue... So strange.

KManager configured to show AFR readings.
Attached you find the start calibration and datalog for this.

Please be patient - it is going to take about two weeks before we can test this.

Anybody get one of these working on the serial inputs? I'm in the middle of removing my PLX sensors and replacing them with AEM. The PLX weren't visible in sunlight (convertible) and frequently failed to work. I loved the serial output though.

I searched quite a bit, but the closest answer I could find is trying to use a RS232 to TTL converter with 12to5V power supply to convert the signal format to something the KPro can take in. Alternately, voltage level conversion on the IN- input. Given that the KPro4 has TTL, RS232, and CAN IO, this seems like a lot of work for something that should be plug and play. Thoughts?

Thanks.

Hi,

Was anyone able to solve the problems they are having?

Have a KPro v4 with the same wideband sensor and the sensor is emitting the signal but the Kpro is not interpreting the data correctly also. What were the settings used?

Thanks

Hello.

Did you find a solution ?

Because I just got this AEM 30.0300 probe to replace a oem narrowband on a PRA ECU and Kpro V4.

My schematic is correct ?


Thanks everyone.

Hello, im having issues with my kpro v4. I installed an aem 30-0300 wideband. It was working good for a few days. We were tweaking something with the rev limiter and now the kpro is not reading what the wideband has. The wideband works but he expropriation is just not reading it. Please help 🙏

Without the calibration and datalogs showing the issue it is hard to say what is happening.

I figured it out. In the options>settings>wideband input i had to put it to custom and play around with the voltage. Now the kpro is reading around 16's and my aem is around12.9. What can I do to make those numbers closer ?

Does the AEM display match what it is reading in the Hondata software?
